Just got off the ship and I can definitely ditto all the good reviews. The ship was fabulous, the food very good and the entertainment was extraordinary--nothing like it on the high seas and this was our 15th cruise on various lines. Here are some tips for cruising on the Oasis.
1. The electrical outlets are not very convenient--one behind night stand and one under and on the side of the desk. I'd suggest taking a power strip to use for recharging cameras, cell phones, etc. It can be plugged in under the desk and then set on top of the desk. Much more convenient than bending down to reach the plug. We had a Central Park View cabin.
2. I took a 12' extension cord so I could use my hairdryer in the bathroom. I was able to plug it in behind the bed/nightstand and then extend it over the bed to reach the bathroom.
